Family and friends of victims killed in a suicide attack on a Kurdish wedding gather to pay their respects to the dead.

Turkish authorities have identified 44 of the 51 people killed on Saturday after a child suicide bomber targeted a Kurdish wedding ceremony in the Turkish city of Gaziantep along the Syrian border.

All of the identified victims were laid to rest in Gazinantep on Sunday.

"Every type of death is painful. But it is even more painful when it comes with religious slogans. It is even more painful when they mix religion with politics," said Omer Emlik, who said he was an uncle of two of the victims.

At least 29 of the blast's 44 identified victims were under the age of 18, with 22 of them under 14, a Turkish official said.

Turkish President Recep Tayyip Erdogan said the Islamic State of Iraq and the Levant (ISIL, also known as ISIS) was suspected of orchestrating the attack.
